Abstract:
The curing behavior of an epoxy/clay nanocomposite system composed of diglycidyl ether of bisphenol A (DGEBA) epoxy resin with a new aromatic diamine curing agent and organically modified clay was investigated. Epoxy/clay nanocomposite samples were prepared by mixing DGEBA, different percentages of nanoclay (1, 3, 5, 7, and 9%) and 4-(4-(2,6-diphenylpyridin-4-yl)phenoxy)benzene-1,3-diamine (DAP). The optimum ratio of the epoxy/clay nanocomposite system (3%) was investigated by total enthalpy of the curing reaction from differential scanning calorimetry (DSC) thermograms. The kinetic parameters such as activation energy, pre-exponential factor, and rate constant were obtained from DSC data.
